I need to develop a custom widget to display posts, based on their ID. The user must be able to handpick posts. Right now, they can enter the post ID, but it is not convenient for them.
Is it possible to use the Search form that appears on the Post Edit interface when creating a hyperlink instead of brewing my own solution and reinvent the wheel ? Here is a screenshot of the interface. In this example, the interface autopopulates via Ajax a list of posts relevant to the searched term.
